OCaml version

This is the most recent version of the software. We switched our implementation language to OCaml to improve performance, and to have access to the distribution source (so we could run on Ethernet without IP). The distribution contains source code and documentation. To properly build the software, you will need:

OCaml 3.01, an ML dialect
See The Caml page for general information, or grab the distribution. Files here are in a number of formats ( tarred/gzipped, i386 RH 6.2 RPM, etc.). Note that the PLAN software may not work with versions of OCaml other than 3.01.
CamlP4, a preprocessor of Caml, version 3.01.6
General information or the distribution.
OCaml patch to enable Ethernet access on Linux machines (optional)

For detailed installation instructions, please refer to the PLAN installation manual.

Once you have installed the software, we suggest you proceed with the PLAN tutorial.

Java version

The distribution contains the Java class files, source code, and documentation. To run our interpreter, you will at a minimum need:

A Java 1.1 interpreter
Try Sun's JDK 1.1 or the JDK 1.1.1 Linux port
The Pizza class files
Available at Pizza Home Page

In order to compile our code from the source, you will additionally need:

The JavaCC Parser Generator
version 0.6.1, available here. This differs from the newest version available at Sun's Java Compiler Compiler Page

For detailed installation instructions, please refer to the PLAN installation manual.

Once you have installed the software, we suggest you proceed with the PLAN tutorial.

You may add a router to this network very easily. Simply specify switchlet.cis.upenn.edu as the master when starting your router (see the tutorial for more). This network is running on the default port (3324).
